Indicates that a ParallelTimeline will not slip with the child Timeline, but will expand to fit all slipping Timeline children. NOTE: This is only effective when the Duration of the ParallelTimeline is not explicitly specified.

Slip

Indicates that a ParallelTimeline will slip along with its first child Timeline that can slip whenever that child is delayed or accelerated..

You can use one or more MediaTimeline objects in a Storyboard together with other Timeline objects, such as animations.

The following example sets the SlipBehavior property of the Storyboard to a value of Slip, which specifies that the animation does not progress until the media (video in this example) progresses. This functionality might be needed if media playback is delayed because of loading time.
